[Feature Request] Z offset test request

[true911m]

Hi, I'm new to 3D and while I'm walking through your calibration steps and watching lots of YouTube (including yours - thank you!) I've seen some recommendations on how and why to calibrate the Z offset for first layer adhesion and consistency. There are print tests out there, but I thought that test would fit perfectly into a tool like this, showing variations in a single print like the temperature and retractions prints do, only across a flat surface. Here's hoping you'll consider it!
